SPECIFICATION forming part of Letters Patent No. 773,344, dated October25, 1904.

Application filed May 24, 1904. Serial No. 209,516. (No model.)

' State of Pennsylvania, have invented certain new and usefulImprovements in Telescopic Horns, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements intelescopic horns, and has for its object the provision of novel meanswhereby horns may be telescoped and securely retained in the collapsedposition.

The present invention relates to all forms of horns, such as are usedfor phonograph's, graphophones, musical instruments, and the like; andone of the many objects of my invention isto produce a horn that may beextremely simple in construction, strong, durable, comparativelyinexpensive to manufacture, and highly eflicient in its use.

My invention broadly consists in the novel construction. combination,and arrangement of parts to be hereinafter more specifically described,and fully pointed out in the claims.

In describing the invention in detail reference is had to theaccompanyingdrawings, forming a part of this application, and whereinlike numerals of reference indicate like parts throughout the severalviews, in which- Figure 1 is a vertical sectional view of my improvedhorn, showing the horn in the eX- tended position. Fig. 2 is a similarview showing the horn in the collapsed position. Fig. 8 is an enlargeddetail view of the joint, show-- ing a vertical sectional view thereof.Fig. 4 is a similar view of the lid. Fig. 5 is atransverse sectionalview taken on the line 5 5 of Fig. 1. Fig. 6 is a longitudinal sectionalView of the funnel portion of the horn. Fig. 7 is a cross-sectional viewof the funnel. Fig. 8 is a perspective view of one of the parts of thefunnel, and Fig. 9 is an end view thereof.

In the drawings, the reference-numeral 1 represents the mouthpiece, 2and 3 integral sections, and 4 the bell of the horn, these sections 1,2, 3, and 4 being constructed in a manner as to permit the horn toreadily telescope one section within the other. The section 3 carries atits enlarged end flanges 5 5, which are slightly curved, as shown at 6,to receive a lid or cover 7, which is adapted to form a lockingengagement therewith, said lid carrying a handle 8. The sections 1 and 2when in the collapsed position are inclosed within the section 3 and areheld in this position by means of the lid or cover 9, carrying flanges10, which are adapted to lock in the recesses 11, the latter beingslightly curved, as shown in Figs. 1 and 2 of the drawings. The jointbetween the sections isformed by the curved depressed portion 12 and asimilar raised portion 14L fitting therein.

The funnel-shaped portion 1 of the horn comprises a plurality ofsections 15, a portion of their edges being curved, as indicated at 16and 17, whereby each section may be secured one within the other,forming a funnel-shaped horn, and the rear end of these sections havetheir curved edges cut away,

as indicated at 18, whereby each section may 7 22 of the funnel-shapedportion of the horn.

In Fig. 7 I have illustrated how the different sections 15 are securedtogether by means of the curved edges 16 and 17, and while I have hereinshown this construction of funnel for horns it is obvious that I mayreadily employ the'form of funnel illustrated in Fig. 1 of the drawingsand that the convenience of handling the horn where it comprises aplurality of sections will be readily appreciated by those who have usefor the same, and the many other advantages obtained by the use of thisinvention will 'be apparent from the foregoing description, taken inconnection with the accompanying drawings.

It will be obvious that various slight changes may be made in thedetails of. construction without departing from the general spirit of myinvention.

Having fully described my invention. what I claim as new, and desire tosecure by Letters Patent, is

1. A horn composed of a plurality of telescopic sections, a lid on eachend of the outermost of said telescopic sections to inclose theremaining section, substantially as described.

2. In a horn, the combination of a plurality of telescopic sections ofgradually-increasing size, and a bell-mouth secured to the largestsection, with two lids, one fitted to the smaller end of the largestsection, the other titted to the larger end of the same section andwithin the bell-mouth.

3. A horn composed of a plurality of telescopic sections having curvedgrooves formed therein, and corresponding raised portions formed in theopposite sections adapted to extend into and lit said grooves, one ofsaid sections composed of a plurality of sections, each last-mentionedsection having its edges curved whereby said sections may be securedtogether, and means whereby said sections may be secured to the othersections, substantially as described.

In testimony whereof I allix my signature in the presence of twowitnesses.
